Hardell and his team find increasing evidence of brain tumour risk associated with mobile phone use
27th August 2010
A new study by Hardell, published in June 2010, found that using a mobile phone for more than 10 years more than doubled the risk of developing a brain tumour, and the more hours the phone was used, the higher the risk. For those who had used their phone for more than 2,000 hours in total since they first started using the phone, the risk was more than tripled. More than 2,000 hours on a cordless phone was also associated with nearly a doubling of brain tumour risk.
This has serious consequences for our young people, who will exceed the 2,000 hours since they first began to use a phone pretty quickly. A previous article by Hardell and Carlberg, published in 2009, showed that the people at greatest risk were those who had first used a mobile phone under the age of 20.
Say half an hour a day on average (low for many young people). That's 3.5 hours a week (at least). 175 hours a year will add up to 2,000 hours in 10 or 11 years after first using the phone, increasing the risk of developing a malignant brain tumour by more than 3 times.
Many young people use text messaging rather than holding the phone to their ear, but as this pattern of behaviour was not allowed for in the study, it seems that the risk may have been underestimated, as the number of hours they held the phone to their head was less than the hours used overall.

Be aware of your family's mobile phone use. It is not worth just hoping that Hardell and many others are wrong. If necessary buy those you are concerned about a Blocksock to reduce the exposure to their brain.
We feel it is important that people should use a wired phone whenever possible to reduce the risks they are exposing themselves to when they use a wireless phone (mobile or DECT).
Ten years may seem like forever to a young person, but it soon slips by. We will soon be experiencing a rise in brain tumour incidence, that could feel like an epidemic as we enter the time of 10 years after mobile phones became commonly used by adults and then children.
Listen to what the authorities in different countries say about reducing your exposure because of the health risks, outlined in the article library on the EMFields site on 'Mobile Phones' and 'Children and Mobile Phones'.
